Demi Glace is traditionally derived from Espagnole. Classic demi is a mixture of equal parts espagnole and veal stock, reduced to the proper consistency. Nowadays, we generally refer to any reduced and/or fortified veal stock as demi.
Is buerre blanc a classic mother sauce? No. But I'm ok with it being considered a modern mother sauce, a la Brown, White and emulsion. That sounds like a good way to update the traditional thinking of a mother sauce.
Ed, Buerre Blanc IS an emulsion. Butter itself is an emulsion (fat suspended in water), so buerre blanc is simply a way to "melt" the butter while maintaining the natural emulsion of the butter.
Veloute is not bechemel with stock. Bechemel is milk, thickened with roux, and simmered with an onion piquet until the flour taste is cooked out. Veloute is made with white stock (chicken, veal, or fish) and roux.
